Hello,
I've a little problem. I began a new project where I've to use Kdevelop. So I
thought it is a good idea to work with cmake-project and the posix skin to get
a more commone code. I want to use RTnet for my communication. But I think that
Xenomai don't use the RTnet-Driver. I got the message:
"Cannot assign requested address" from the function "ret=recvfrom(socket,
&buffer, sizeof(buffer), (struct sockaddr *)&dest_addr, &sizeof(dest_addr))"
I think the problem is that Xenomai use the standart recvfrom and the standart
recvfrom can not recognize the realtime driver. I use the following cmake file:
PROJECT(robotclient)
cmake_minimum_required(VERSION 2.8)
set(Robot_Client_VERSION_MAJOR 1)
set(Robot_Client_VERSION_MINOR 0)
set(XENOMAI_SEARCH_PATH "/usr/xenomai" "/usr/local/xenomai")
find_path(${XENOMAI_DIR} "include/xeno_config.h" ${XENOMAI_SEARCH_PATH})
IF(${XENOMAI_DIR})
set(XENOMAI_INCLUDE_DIR ${XENOMAI_DIR}/include)
set(XENOMAI_INCLUDE_POSIX_DIR ${XENOMAI_DIR}/include/posix)
find_library(XENOMAI_LIBRARY_XENOMAI xenomai ${XENOMAI_DIR}/lib)
find_library(XENOMAI_LIBRARY_PTHREAD_RT pthread_rt ${XENOMAI_DIR}/lib)
find_library(XENOMAI_LIBRARY_RTDM rtdm ${XENOMAI_DIR}/lib)
find_library(XENOMAI_LIBRARY_RT rt ${XENOMAI_DIR}/lib)
set(EXTRA_LIBS ${EXTRA_LIBS} ${XENOMAI_LIBRARY_XENOMAI})
set(EXTRA_LIBS ${EXTRA_LIBS} ${XENOMAI_LIBRARY_PTHREAD_RT})
set(EXTRA_LIBS ${EXTRA_LIBS} ${XENOMAI_LIBRARY_RTDM})
set(EXTRA_LIBS ${EXTRA_LIBS} ${XENOMAI_LIBRARY_RT})
find_file(XENOMAI_POSIX_WRAPPERS lib/posix.wrappers {XENOMAI_SEARCH_PATH})
set(XENOMAI_EXE_LINKER_FLAGS "-W1,@${XENOMAI_POSIX_WRAPPERS}")
set(CMAKE_EXE_LINKER_FLAGS ${CMAKE_EXE_LINKER_FLAGS}
${XENOMAI_EXE_LINKER_FLAGS})
set(XENOMAI_DEFINITIONS "-D_GNU_SOURCE -D_REENTRANT -Wall -pipe -D__XENO__")
set(EXTRA_DEFINITIONS ${EXTRA_DEFINITIONS} ${XENOMAI_DEFINITIONS})
include_directories(${XENOMAI_DIR}/include)
include_directories(${XENOMAI_DIR}/include/posix)
ENDIF(${XENOMAI_DIR})
ADD_DEFINITIONS(${EXTRA_DEFINITIONS})
ADD_EXECUTABLE(robotclient main.cpp)
TARGET_LINK_LIBRARIES(robotclient ${EXTRA_LIBS})
Is there something wrong?
regards,
franz
